Heat a Dutch oven over medium-high heat. Coat pan with cooking spray. Add beef to pan; cook 4 minutes or until browned, stirring frequently. Remove beef from pan. Add carrot, celery, onion, and mushrooms to pan; cook 6 minutes or until liquid almost evaporates. Add beef; fat-free, less-sodium beef broth; and bay leaf. Bring to a simmer over medium-high heat.
